Curse my speedy metabolism, for I will never be an effective sumo wrestler. But now at least I can live vicariously through these little R/C sumos. You get your very own ring, two wrestlers and two remotes. Now all you need is 10 AAA batteries and you're ready to wrestle.
On another note, during the slow-motion scene at the end of the video did anyone notice anything strange about the sumo's feet? Yeah, weird.
